# Umchazandalo

izibonelo ezihlukene zesimongotho
**Umchazandalo** uyinzululwazi yemvelo ecwaninga utho, izakhi zalo eziyisisekelo, umdiki walo nokucondoza kwalo emkhathini nasesikhathini, kanye nokuhlobana kwesidlakalasi nesiphoqi . Umchazandalo ongesinye sezifundo zenzululwazi eziyisiseko, nesimpokompelo yaso eyinhloko kuwukuqonda ukuthi umkhathilibe ucondoza kanjani. Usonzululwazi ongungoti emkhakheni womchazandalo ubizwa ngokuthi umfundindalo.

Umchazandalo ungesinye sezifundo ezindala kakhulu, futhi, uma sihlangene nomchazamkhathi, cishe kuba esidala ukwedlula zonke. Phezu kweminyaka eyizinkulungwane ezimbili ezidlule, umchazandalo, umchazatho, umchazampilo, kanye namanye amagatsha womchazazibalo zaziyingxenye yenjulalwazi yemvelo, kodwa ngesikhathi seNguquko yezenzululwazi ekhulwini le-17 lezinzululwazi zafufusa njengocwaningo oluyingqayizivele oluzimele ngokwalo. Umchazandalo ucobelelana nezifundo eziningi, ezifana nomchazandalo wempilo *(biophysics)* kanye nomchazatho womngako *(quantum chemistry)*, futhi imikhawulo yomchazandalo echasisiwe yaqondakala. Amasu amasha kumchazandalo imvama achaza izindlela eziyisiseko ezifundwa ezinye izinzululwazi futhi asikisela izindlela ezintsha zocwaningo kuzo nakwezinye izifundo ezifana nomchazazibalo nenjulalwazi.

Izintuthukiso kumchazandalo imvama zivulela Izintuthukiso kwezobuchwepheshe ezintsha. Ngokwesibonelo, Izintuthukiso ekuqondeni inzubawonga, umchazandalo wesimo esilukhumanqa, kanye nomchazandalo wenuzi kwaholela ngokuqondile ekuthuthukisweni kwemikhiqizo emisha eyaguqula umphakathi wanamuhla, efana nomabonakude, iziCikizi, izinsiza zasendlini, kanye nezikhali zenuzi; Izintuthukiso kwezomchadamezo *(thermodynamics)* zaholela ekuthuthukisweni kwezezimboni; futhi Izintuthukiso kwezezinguxa kwafaka ugqozi ekuthuthukisweni koqaqulo *(calculus)*.

## uMlando

Igama elithi "umchazandalo" liyinhlanganisela yamabizo amabili, isenzo esisho 'ukuchaza' + nebizo elithi 'indalo'.

### uMchazamkhathi wasendulo

uMchazamkhathi waseGibhithe uyabonakala kumphezulu womchazamkhathi osethuneni lika-Senemut, langenkathi yosendo lweshumi nesiphohlongo
Umchazamkhathi ungenye yezinzululwazi zemvelo ezindala. Imiphakathi yasendulo eminyakeni eyizi-3000 BCE efana neyabase-Sumeriya, iGibhithe lasendulo, kanye nemiphakathi yasesiGodini se-indus, yayinolwazi kanye nokulumuka oluyisiseko lomdiki welanga, inyanga nezinkanyezi. Izinkanyezi nemizulane, okwaku nenkolelo yokuthi zimelela izinyanya, zazivame ukukhulekelwa. Kuyilapho izincazelo zalezimiso eziqaphelwayo zezinkanyezi zazingahambisani nenzululwazi futhi ziswele ubufakazi, lezingqaphelo zakuqala zavela isisekelo zomchazamkhathi wakamuva, njengoba izinkanyezi kwatolwa ukuthi zizungeza esibhakabhakeni.

Indabuko yomchazamkhathi wasentshona itholakala eMesophothamiya, futhi imizamo yasentshona yenzululwazi enembayo itholakala kumchazamkhathi waseBhabhiloni. Umchazamkhathi waseGibhithe washiya izingqophamlando esiveza ulwazi lwemithala kanye nomdiki wezindikimba zasezilwini, kuyilapho usozinkondlo waseGrisi uHoma wabhala ngezinto zasemkhathini ezihlukile kwinkondlo ebizwa *[Iliad* nethi *Odyssey*; kamuva ongaqayinga bamaGriki bafaka amagama, okuyiwona asasetshenziswa ngolimi lwesingisi, azo yonke imithala ebonakala ngenhla nenkabazwe.

### INjulalwazi yemvelo

INjulalwazi yemvelo indabuko yayo isezweni laseGrisi ngesikhathi sasendulo (650 BCE – 480 BCE), lapho izingcithabuchopho zangaphambi kuka-Sokrati ezifana noThalesi zaqantuza izincazelo ezingezona ezemvelo ngesimongotho semvelo futhi zamemezela ukuthi zonke izehlakalo zazisisusa esingokwemvelo. Zaphakamisa amasu aqinisekiswa ngokuhluzwa nangokuqapha, futhi izihlawumbiselo zabo eziningi zaba yiqiniso ngokomgcanao; ngokwesibonelo, ubuchwe batholwa njengonembile emacishelweni eminyaka eyizi-2000 ngemuva kokuphakanyiswa ngu-Lesiphasi nomfundi wakhe uDemokritasi.

### EYuruphu nobuSulumane benkathi ephakathi

U-Ibn al-Haytham cishe ngowama-965-1040 wabhala umgcanso obizwa *camera obscura* encwadini ethi *Book of Optics*.
Umbuso waseRoma waseNtshona Wawa ngekhulu lesihlanu futhi lokho kwaba nemiphumela ekuncipheni kokuphishekelwa kobuhlakani engxenyeni esentshona neYuruphu. Ngokuphambene, umbuso waseRoma waseMpuma wona wawumelene nokuhlaselwa ngamaqaba, futhi uqombola ezindimeni ezihlukene zemfundo, kuhlanganisa nomchazandalo.

Ekhulwini lesithupha, u-Isidoli waseMilitu wadala Iqoqo elibalulekile lemisebenzi ka-Akhimendesi efaniselwe kwi-*Archimedes Palimpsest*. Izazi zamaSulumane zazisebenzisa umchazandalo kaAristotile kakhulu owawubuya eGrisi, futhi zawuthuthukisa kakhulu.

Ucandululo oluphawulekayo lwezazi zamazSulumane lwalusemkhakheni womkhanyizo nombono, owawubuya emisebenzini yosonzululwazi abafana no-Ibn Sahl, u-Al-Kindi, u-Ibn al-Haytham, uKamāl al-Dīn al-Fārisī|Al-Farisi no-Avicenna. Encwadini yakhe ethi Incwadi yomkhanyizi (ebizwa Kitāb al-Manāẓir) u-Ibn al-Haytham wethula isu lemisebe yokukhanya esikhundleni sombono wamaGriki wemisebe yombono. NjengoPtolemy, u-Ibn al-Haytham wayesebenzisa imigcanso elawulwayo, eqinisekisa imithetho yokugwincizeka nokukhwentuka nesicabamgo esisha semisebe yokukhanya, Kodwa engenaso Isicabango sokwakheka komfanekiso..

Indlela eyisisekelo isithwebuli se-obscura esisebenza ngayo

### Inguqulo yenzululwazi

Umchazandalo waba Inzululwazi ehlukile lapho osonzululwazi besebenzisa imigcanso nendlelasu engakanisayo ukuze bavubukule lokho namuhla esithi imithetho yomchazandalo.Template:Page needed

Imivubukulo eyinhloko kulenkatho ihlanganisa ukufakelelwa konongo lozungezohlelo lweLanga oluthi inkaba yilanga *(heliocentric)* kaKhopenikhasi, esikhundleni sonongo oluthi inkaba wumhlaba *(geocentric)* , imithetho kaKepler yomdiki wemizulane, umsebenzi kaGalileo wesihlongamkhathi noMchazamkhathi weziqaphelo, nemivubukulo kaIsaac Newton nokuhlanganiswa kwemithetho yomdiki nemithetho yomnyondo, nesifunda somchazazibalo senguquko eqhubekayo, nendlela uNewton asisebenzisa ngayo ezinkingeni zoqobo.

* uGalileo Galilei(1564–1642) wahlobanisa umchazazibalo, umchazandalo ochachiswayo nowemigcanso.
* uJohannes Kepler (1571–1630) wachaza umdiki wemizulane,
* u-Isaac Newton wavubukula imithetho yomdiki nomthetho womnyondo

### 19th century

Nazi Izinto ezavubukulwa futhi zachazwa ekhulwini le-19.

* Imithetho yomchadamezo, imithetho yomchazatho nemithetho yenzubawonga.
